Methyl 2-fluoroacrylate | CAS 2343-89-7

An acrylic monomer with fluorine directly on the polymerizable double bond, suited to fluorinated polymer research where monomer identity and stabilization require explicit control.

CAS2343-89-7
Molecular formulaC4H5FO2
Molecular weight104.08 g/mol

Product overview

The fluorine atom in methyl 2-fluoroacrylate is attached to the alpha carbon of the acrylic group; the ester group remains methyl. This architecture differs from acrylates carrying a fluorinated alcohol residue. As a small, unsaturated ester, it is supplied in stabilized reference grades, and the inhibitor package is part of its practical specification for polymerization work.

Application context

TCI classifies this compound among fluorinated acrylic monomers. It provides a starting point for polymer and copolymer development that introduces fluorine through the monomer’s vinyl group. Selection should be based on the required repeat-unit structure and the planned polymerization system. Inhibitor concentration, monomer purity and the presence of preformed oligomer need to be assessed before interpreting conversion or formulation results.

Chemistry and synthetic role

Its CH2=C(F)–COOCH3 structure places fluorine at the reactive alkene carbon rather than in the ester side chain.

Quality review

Correct fluorinated structure

Confirm alpha-fluoro substitution and exclude confusion with fluoroalkyl acrylate esters.

Stabilization

State inhibitor identity and level; published BHT-stabilized grades are examples, not a universal composition.

Monomer condition

Agree chromatographic purity and suitable controls for water, free acid and nonvolatile material.

Preparing a specification

Specify methyl 2-fluoroacrylate, inhibitor composition, monomer assay and limits relevant to hydrolysis or premature polymerization.

Packaging and storage

Confirm container compatibility, closure and net weight for the selected grade and destination. Follow the actual supplier SDS and batch label for storage and transport.

Documentation

Request the batch COA, SDS and analytical methods covering the agreed purchasing specification. Confirm which supporting chromatograms and application-specific records are available from the selected manufacturer.

Procurement questions

Is it a fluoroethyl acrylate?

No. Its ester is methyl; fluorine is attached to the acrylic double bond.

Does inhibitor content matter for polymerization?

Yes. Include it when qualifying the material against the intended initiator and process.

Does monomer purity establish polymer performance?

No. Copolymer composition, conversion and processing must also be evaluated.
